Definitions
- the present invention relates to cursors for waveform/graphics displays, and more particularly to touch control of cursor position for a display device using a touch sensitive display screen.
- cursors are positioned on displays by using buttons and knobs at a control panel. In this manner a cursor, which is a pointer to a particular point on a display identifying a feature of interest, may be moved to any point on the display screen. For waveform display devices this means that the cursor may be positioned at a particular point on a waveform so that certain information about that point, such as magnitude, or in reference to that point, such as duration, may be determined.
- Touch screens are commonly used in display devices to select items from a menu displayed on the screen, or to select a region of a display for further processing.
- An example of further processing is a zoom function which may be implemented about a contact point on a touch screen, as disclosed in U.S. Patent No. 4,755,811 issued July 5, 1988 to Keith R. Slavin entitled “Touch Controlled Zoom of Waveform Displays” and incorporated in the VM700 Video Measurement Set manufactured by Tektronix, Inc. of Wilsonville, Oregon, United States of America.
- JP-A-1125612 discloses a cursor at one point on the screen that can be replaced by a "touch" mark where the screen is touched, which may be an entirely different position on the screen from the cursor mark.
- the "touch” mark can be dragged to a desired position and when contact is removed from the screen, the "touch” mark reverts to a cursor mark.
- the present invention provides a method for touch control of cursor position for a display device using a touch sensitive screen.
- an operator touches the screen at the current position of the cursor with an appropriate pointer, such as a finger.
- Contact with the screen initiates a search to determine what is at the contact point on the display within a tolerance range. If the cursor is determined to be at the point of contact, then the display device enters a cursor mode so that further activities are related to the cursor.
- the pointer is dragged across the screen, the position of the cursor is recalculated to remain underneath the pointer so that the cursor appears to move with the pointer. In this manner the cursor position is controlled by touching the screen.
- the pointer breaks contact with the screen, further movement of the cursor in the cursor mode made be made conventionally with a knob.
- Fig. 1 is a block diagram of a display device that uses touch control of cursor position according to the present invention.
- Figs. 2A and 2B illustrate the operation of touch control of cursor position according to the present invention.
- Fig. 3 is a flow chart for the touch control of cursor position according to the present invention.
- a test instrument 10 is shown of the type for acquiring and displaying waveform characteristics of an input electrical signal.
- any display device including graphics display devices, may use the touch control of cursor position as disclosed herein.
- All acquisition system 12 receives an analog signal and converts it to a digital signal for storage in an acquisition memory 14 .
- the signals may be input directly into the acquisition memory 14 .
- a display processor 16 has a bus 18 to which the acquisition memory 14 is coupled.
- the display processor 16 includes a processor unit 20 and a program memory 22 .
- the display processor 16 processes the data in the acquisition memory 14 and stores the processed data in a display memory 24 .
- the data from the display memory is then displayed by the display processor 16 on a screen 26 .
- All operator interacts with the display processor 16 via an appropriate interface 28 , such as a keyboard, mouse, touch screen on the screen 26 , controls on a front panel 30 , or the like.
- the display processor 16 provides a cursor 32 for the display in the form of either a vertical or horizontal line or other appropriate icon, as is well known in the art.
- the cursor 32 is stored with the acquired data in the display memory 24 .
- the initial position of the cursor 32 may be at the center of the screen 26 , or at the upper left hand corner of the screen, or other predetermined position.
- an operator touches the screen 26 at the current cursor position (1) with an appropriate pointer 34 , such as a finger shown in Fig. 2b.
- an appropriate pointer 34 such as a finger shown in Fig. 2b.
- Contact with the screen 26 initiates a search procedure that uses the coordinates of the contact point.
- the display processor 16 compares the contact point with the current position of the cursor 32 , which is maintained in the display processor. If the current cursor position corresponds to the contact point, then a cursor mode is initiated. The initiation of the cursor mode may be indicated on the screen by a change in the representation of the cursor 32' by the display processor 16 , such as changing the representation from a dotted line to a solid line or a flashing cursor icon to a steady icon.
- the cursor mode which includes assigning a control knob to the cursor 32' , all further movement of the point of contact by the pointer 34 is processed by the display processor 16 as affecting the position of the cursor on the display as if it were the control knob that was being rotated.
- the display processor 16 updates the cursor data in the display memory 24 by rewriting it in a new position corresponding to the new contact point (2) of the pointer 34 on the screen 26 when the display memory is updated from the acquisition memory 14 .
- the cursor mode may be combined with the zoom mode, described in the aforementioned U.S. Patent No. 4,755,811, so that zoom occurs about the current contact point and the cursor is positioned closer to the point of interest as zoom occurs. Once contact is broken with the screen 26 , further movement of the cursor 32 may be controlled conventionally by the control knob.
- the present invention provides touch control of cursor position by determining whether a contact point on a display screen coincides with a current cursor position, and then updating the cursor position as the contact point moves across the display screen.
